Tried and Tru

New Tru-Design Thru-Hull fittings are built to last the lifetime of the vessel. Built with chemical-resistant fittings, they are impervious to diesel, oil and antifouling paints. Made from a glass-reinforced composite, these through-hulls are strong yet lightweight. The material is also immune to corrosion and electrolysis, resulting in a longer life. They’re suitable for all marine environments and hull types, including aluminum, steel, wood and GRP. Tru-Design Thru-Hull fittings are available in half-inch through two-inch sizes and in threaded, recessed or with tail models.
